A Day in the Woods in Pregnancy: Fetal and Neonatal Implications.

Borrelia miyamotoi disease (BMD), also known as hard-tick relapsing fever, is an emerging tick-borne illness caused by the bacterium Borrelia miyamotoi.

BMD poses significant public health concerns because of its potential to cause severe hemodynamic and hematologic disturbances, particularly in vulnerable populations such as pregnant individuals.
